연결 코드:

class MyApi

  URI = nil #base api uri
  attr :connection

  def initialize(opts = {})
    <strong i="6">@uri</strong> = opts[:uri] || URI
    <strong i="7">@key</strong> = opts[:key] || get_key(opts[:username], opts[:password])
    raise ConnectionError, 'no api key' unless <strong i="8">@key</strong>

    <strong i="9">@connection</strong> = Faraday.new(@uri) do |b|
      b.adapter Faraday.default_adapter
      b.request :json
      b.response :logger
      b.response :raise_error
      b.response :json, :content_type => "application/json"
    end
    @connection.headers['X-ApiToken'] = <strong i="10">@key</strong>
  end
end

그래서 내가 할 경우 :

api = MyApi.new(key)
api.connection.put("forms/#{id}.json", params)
